Beschreibung description
Die Erfindung betrifft ein Solarmodul nach dem Oberbegriff des Anspruchs 1, ein Verfahren zur Herstellung eines derartigen Solarmoduls nach dem Oberbegriff des Anspruchs 16, sowie die Verwendung eines derartigen Solarmoduls nach dem Anspruch 20. The invention relates to a solar module according to the preamble of claim 1, a method for producing such a solar module according to the preamble of claim 16, and the use of such a solar module according to claim 20.
Bei Solarmodulen der gattungsgemässen Art, wie sie beispielsweise in der DE-OS 2 942 328 oder der EP-OS 0 382 060 beschrieben sind, besteht, wie dies schon in der älteren DE-OS 4 029 822.1 dargelegt ist, das Problem, dass insbesondere infolge der häufig im Siebdruckverfahren hergestellten, verhältnismässig dicken bzw. breiten Anschluss-und Verbindungsleiter für die einzelnen verschalteten Solarzellen die Aussenansicht den gestellten ästhetischen und insbesondere architektonischen Anforderungen, vorzugsweise bei Verwendung als Fassadenelement, nicht genügt. Es ist bereits vorgeschlagen worden, z.B. in der EP-OS 0 343 628 und der DE-OS 4 029 822.1, die Beeinträchtigung des ästhetischen Gesamteindruckes des Solarmoduls durch die Leiterstruktur, jedoch auch durch die technischen Einzelheiten der Solarzelle selbst, welche durch die transparente Aussenscheibe erkennbar sind, dadurch zu mildern, dass eine zumindest bereichsweise Farbbedruckung vorgesehen oder eine farbige oder mattierte Zwischenschicht verwendet wird. Die EP-OS 0 343 628 lehrt diesbezüglich insbesondere eine Randbedruckung, welche die Verbindungsleiteranordnung am Solarmodulrand abdecken kann. In the case of solar modules of the generic type, as described, for example, in DE-OS 2 942 328 or EP-OS 0 382 060, there is the problem, as already stated in the older DE-OS 4 029 822.1, that in particular As a result of the relatively thick or wide connecting and connecting conductors for the individual connected solar cells, which are often produced using the screen printing process, the exterior view does not meet the aesthetic and in particular architectural requirements, preferably when used as a facade element. It has already been suggested, e.g. in EP-OS 0 343 628 and DE-OS 4 029 822.1 to alleviate the impairment of the overall aesthetic impression of the solar module by the conductor structure, but also by the technical details of the solar cell itself, which can be recognized by the transparent outer pane, that color printing is provided at least in some areas or that a colored or matted intermediate layer is used. In this regard, EP-OS 0 343 628 teaches in particular an edge print which can cover the connecting conductor arrangement on the edge of the solar module.
Die bekannten Versuche zur Verbesserung des ästhetischen Eindrucks von Solarmodulen der gattungsgemässen Art haben jedoch sämtlich den Nachteil, dass hiermit stets eine deutliche Ausbeuteverringerung verbunden ist, weil sowohl durch eine Bedruckung von Teilbereichen als auch durch Mattierung oder Opakisierung der dem Lichteinfall zugewandten Aussenscheibe die Lichtdurchlässigkeit verringert wird. Eine derartige Ausbeuteverringerung ist natürlich bei Solarmodulen vollkommen unerwünscht. However, the known attempts to improve the aesthetic impression of solar modules of the generic type all have the disadvantage that this is always associated with a significant reduction in yield, since the translucency is reduced both by printing on partial areas and by matting or opaqueizing the outer pane facing the light . Such a reduction in yield is of course completely undesirable in the case of solar modules.
Der Erfindung liegt die Aufgabe zugrunde, ein Solarmodul der gattungsgemässen Art, sowie ein Verfahren zu dessen Herstellung, nebst Verwendung des Solarmoduls, anzugeben, bei dem der erwünschte Effekt der Verbesserung des ästhetischen Eindruckes ohne wesentliche Ausbeuteverringerung erzielt werden kann. The invention has for its object to provide a solar module of the generic type and a method for its production, together with the use of the solar module, in which the desired effect of improving the aesthetic impression can be achieved without significant reduction in yield.
Erfindungsgemäss wird diese Aufgabe bei einem Solarmodul der gattungsgemässen Art dadurch gelöst, dass an der Aussen- und/oder Innenseite der Solarenergieumwandlungseinrichtung eine Glasscheibe mit einer Vielzahl von im wesentlichen senkrecht zur Modulebene verlaufenden Bruchflächen vorgesehen ist. According to the invention, this object is achieved in the case of a solar module of the generic type in that a glass pane with a plurality of fracture surfaces running essentially perpendicular to the module plane is provided on the outside and / or inside of the solar energy conversion device.
Dabei kann vorgesehen sein, dass die Aussenscheibe eine Vielzahl von im wesentlichen senkrecht zur Modulebene verlaufenden Bruchflächen aufweist. It can be provided that the outer pane has a plurality of fracture surfaces that run essentially perpendicular to the module plane.
Weiterhin sieht die Erfindung vor, dass die Trägerplatte eine Vielzahl von im wesentlichen senkrecht zur Modulebene verlaufenden Bruchflächen aufweist. Furthermore, the invention provides that the carrier plate has a plurality of fracture surfaces which run essentially perpendicular to the module plane.
Eine weitere Ausführungsform der Erfindung ist dadurch gekennzeichnet, dass zwischen der Solar-energieumwandlungseinrichtung und der Aussenscheibe eine mit einer Vielzahl von im wesentlichen senkrecht zur Modulebene verlaufenden Bruchflächen versehene Zwischenscheibe angeordnet ist. A further embodiment of the invention is characterized in that between the solar energy conversion device and the outer pane, an intermediate pane is provided, which is provided with a plurality of fracture surfaces which run essentially perpendicular to the module plane.
Auch kann vorgesehen sein, dass die Zwischenscheibe mit der Aussenscheibe verklebt ist. It can also be provided that the intermediate disk is glued to the outer disk.
Die Erfindung schlägt auch vor, dass zwischen der Solarenergieumwandlungseinrichtung und der Trägerplatte eine mit einer Vielzahl von im wesentlichen senkrecht zur Modulebene verlaufenden Bruchflächen versehene Dekorscheibe angeordnet ist. The invention also proposes that between the solar energy conversion device and the carrier plate there is arranged a decorative pane provided with a plurality of fracture surfaces which run essentially perpendicular to the module plane.
Eine weitere Ausführungsform des Solarmoduls nach der Erfindung ist dadurch gekennzeichnet, dass die Dekorscheibe mit der Trägerplatte verklebt ist. Another embodiment of the solar module according to the invention is characterized in that the decorative pane is glued to the carrier plate.
Weiterhin schlägt die Erfindung vor, dass die Bruchflächen wenigstens eines der Scheibenelemente des Moduls durch mechanische und/oder thermische, insbesondere randseitige Beanspruchung einer das betreffende Scheibenelement bildenden Einscheibensicherheitsglasscheibe erzeugt sind. Furthermore, the invention proposes that the fracture surfaces of at least one of the pane elements of the module are produced by mechanical and / or thermal, in particular edge-side, stressing of a single-pane safety glass pane forming the pane element in question.
Es kann auch vorgesehen sein, dass die Bruchflächen wenigstens eines der Scheibenelemente des Moduls durch gezielte linienförmige, nach vorgebbarem Muster erfolgende Druckbeanspruchung einer das betreffende Scheibenelement bildenden Glas- oder Kunststoffscheibe erzeugt sind. Provision can also be made for the fracture surfaces of at least one of the pane elements of the module to be produced by targeted line-shaped, compressive stressing of a glass or plastic pane forming the pane element in question.
Die Erfindung schlägt auch vor, dass im Scheibenzwischenraum zwischen der Aussenscheibe und der Trägerplatte eine Kunststoffschicht, wie Verbundfolienkombination, Giessharzschicht oder dergleichen, angeordnet ist, in die die Solarenergieum-wandlungseinrichtung, vorzugsweise ein Solarzellenfeld mit einer Anzahl von durch Verbindungsund Anschlussleitungen verschalteten Solarzellen, insbesondere polykristallinen Solarzellen eingebettet ist. The invention also proposes that a plastic layer, such as a composite film combination, cast resin layer or the like, be arranged in the space between the outer pane and the carrier plate, into which the solar energy conversion device, preferably a solar cell array with a number of solar cells connected by connecting and connecting lines, in particular polycrystalline Solar cells is embedded.
Ferner kann eine Ausführungsform der Erfindung dadurch gekennzeichnet sein, dass die Zwischenscheibe und/oder die Dekorscheibe mit der Aussenscheibe bzw. der Trägerplatte mittels Verbundfoli-e(n) verklebt ist/sind.

vorzugsweise randseitige Beanspruchung einer das betreffende Scheibenelement bildenden Einschei-bensicherheitsglasscheibe oder durch gezielte, lini-enförmige, nach vorgebbarem Muster erfolgende Druckbeanspruchung einer das betreffende Scheibenelement bildenden Glas- oder Kunststoffscheibe erzeugt werden. preferably edge stress of a single pane safety glass pane forming the pane element in question, or by targeted, linear, compressive stressing of a glass or plastic pane forming the pane element in question according to a predetermined pattern.
Auch kann bei dem erfindungsgemässen Verfahren so vorgegangen werden, dass die Bruchflächen zumindest teilweise nach Abschluss des Verbundprozesses durch randseitige mechanische und/oder thermische Beanspruchung des betreffenden Scheibenelementes, wie Stossbeanspruchung mittels eines Körners oder Lasereinstrahlung, erzeugt werden. In the method according to the invention, it is also possible to proceed in such a way that the fracture surfaces are generated at least partially after the end of the bonding process by mechanical and / or thermal stress on the edge of the pane element in question, such as impact stress by means of a punch or laser radiation.
Schliesslich lehrt die Erfindung auch die Verwendung des erfindungsgemässen Solarmoduls als Fassadenelement. Finally, the invention also teaches the use of the solar module according to the invention as a facade element.
Der Erfindung liegt die überraschende Erkenntnis zugrunde, dass es gelingt, ungeachtet des positiven dekorativen Effektes eine Ausbeuteverminderung weitgehend zu vermeiden bzw. diese zumindest deutlich zu reduzieren, indem eines der Scheibenelemente (Aussenscheibe, Zwischenscheibe) an der dem Lichteinfall zugewandten Seite der Solarener-gieumwandlungseinrichtung, im folgenden kurz als Solarzellenfeld bezeichnet, mit im wesentlichen senkrecht zur Modulebene verlaufenden Bruchflächen versehen wird. Beispielsweise kann hierfür an der dem Lichteinfall zugewandten Seite des Solarzellenfeldes, in Lichteinfallrichtung also hinter der Aussenscheibe, eine mit im wesentlichen senkrecht zur Modulebene verlaufenden Bruchflächen versehene Einscheibensicherheitsglasscheibe angeordnet werden, wie sie, nebst der Art ihrer Herstellung, z.B. aus der DE-OS 2 887 806 und der DE-OS 2 008 415, in beiden Fällen allerdings für gattungsfremde Anwendungsgebiete, bekannt ist. Dadurch, dass das betreffende Scheibenelement, beispielsweise also die Einscheibensicherheitsglasscheibe, zwar eine dekorative Struktur aufweist, welche dem Betrachter die dahinteriiegende Solarzellenstruktur weniger deutlich erscheinen lässt, andererseits dieser Effekt jedoch durch im wesentlichen senkrecht zur Modulebene verlaufende Bruchflächen erzeugt wird, gelingt es, sowohl den gewünschten dekorativen Effekt zu erzielen als auch eine Ausbeuteverringerung weitgehend zu vermeiden. Dies beruht einmal darauf, dass durch die im wesentlichen senkrecht zur Modulebene verlaufenden Bruchflächen ein wesentlich geringerer Teil des einfallenden Lichtes in dem betreffenden Scheibenelement, beispielsweise also in der Einscheibensicherheitsglas-scheibe, absorbiert wird, als dies z.B. bei Verwendung lichtstreuender Partikel mit auch quer zur Lichteinfallrichtung verlaufenden Reflexionsflächen der Fall wäre. The invention is based on the surprising finding that, despite the positive decorative effect, it is possible to largely avoid a reduction in yield or at least to reduce it significantly by one of the pane elements (outer pane, intermediate pane) on the side of the solar energy conversion device facing the incidence of light, hereinafter referred to briefly as the solar cell field, is provided with fracture surfaces running essentially perpendicular to the module plane. For example, on the side of the solar cell field facing the incidence of light, i.e. in the direction of light incidence behind the outer pane, a single pane safety glass pane provided with fracture surfaces essentially perpendicular to the module plane can be arranged, as they, in addition to the type of their manufacture, e.g. from DE-OS 2 887 806 and DE-OS 2 008 415, in both cases, however, for non-generic fields of application. The fact that the pane element in question, for example the single-pane safety glass pane, has a decorative structure which makes the solar cell structure behind it appear less clear to the viewer, but on the other hand this effect is produced by fracture surfaces which run essentially perpendicular to the module plane, achieves both the desired To achieve a decorative effect and to largely avoid a reduction in yield. This is due, on the one hand, to the fact that the fracture surfaces, which run essentially perpendicular to the module plane, absorb a much smaller part of the incident light in the pane element in question, for example in the single pane safety glass pane, than is e.g. the case would be the case if light-scattering particles with reflection surfaces also running transversely to the direction of light incidence were used.
Die Dekorscheibe aus vorgespanntem Einscheibensicherheitsglas, die bei einer besonderen Ausführungsform der Erfindung auch zwischen der in diesem Fall ebenfalls aus Silikatglas bestehenden Trägerplatte und der Kunststoffschicht mit dem darin eingebetteten Solarzellenfeld angeordnet wird, hat im Fall einseitig lichtempfindlicher Solarzellen lediglich einen dekorativen Effekt und gibt dem Solarmodul auch von der Rückseite her ein gefälliges Aussehen. Darüber hinaus wirkt diese Dekorschicht im Fall beidseitig lichtempfindlicher Solarzellen in zur Einscheibensicherheitsglasscheibe zwischen der Aussenscheibe und dem Solarzellenfeld analoger Weise. The decorative pane made of tempered toughened safety glass, which in a special embodiment of the invention is also arranged between the support plate, which in this case also consists of silicate glass, and the plastic layer with the solar cell field embedded therein, has only a decorative effect in the case of one-sided light-sensitive solar cells and also gives the solar module a pleasing appearance from the back. In addition, in the case of solar cells which are light-sensitive on both sides, this decorative layer acts in an analogous manner to the single-pane safety glass pane between the outer pane and the solar cell field.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus den Ansprüchen und aus der nachstehenden Beschreibung, in der ein Ausführungsbeispiel anhand der schematischen Zeichnung im einzelnen erläutert ist. Further features and advantages of the invention result from the claims and from the following description, in which an exemplary embodiment is explained in detail with reference to the schematic drawing.
Dabei zeigt die aus einer einzigen Figur bestehende Zeichnung einen zentralen Ausschnitt eines Solarmoduls nach der Erfindung im Schnitt senkrecht zur Modulebene. The drawing consisting of a single figure shows a central section of a solar module according to the invention in a section perpendicular to the module plane.
Wie die Zeichnung erkennen lässt, weist das er-findungsgemässe Solarmodul bei dem dort gezeigten Ausführungsbeispiel eine Aussenscheibe 10 auf, die aus Silikatglas, und zwar Weissglas, besteht. Über eine Kunststoff-Verbundfolie 12 ist mit der Aussenscheibe 10 eine Einscheibensicherheits-glasscheibe 14 aus vorgespanntem Silikatglas verklebt, deren Struktur und Herstellung weiter unten noch näher erläutert werden. Mit der Einscheibensi-cherheitsglasscheibe 14 und einer Dekorscheibe 16, die ebenfalls, wie die Einscheibensicherheits-glasscheibe 14, aus vorgespanntem Silikatglas besteht und ebenso wie diese in der noch weiter unten näher zu erläuternden Weise hergestellt worden ist, steht nach Art der Verbundschicht einer Verbundsicherheitsglasscheibe eine Kunststoffschicht 18 in Verbindung, z.B. als Giessharzschicht ausgebildet, in die ein Solarzellenfeld 20, vorzugsweise aus polykristallinen Solarzellen bestehend, eingebettet ist. Die einzelnen Solarzellen des Solarzellenfeldes 20 sind in in der Zeichnung nicht dargestellter, aber beispielsweise in der DE-OS 4 029 822.1 erläuterten Weise, z.B. auch wie aus der EP-OS 0 382 060 bekannt, miteinander durch Verbindungsleiter verschaltet, wobei weitere Anschlussleiter an den Scheibenrand führen und zum elektrischen Verbinden benachbarter Solarmodule dienen. Die Anschluss- und Verbindungsleitungen, welche in der Zeichnung nicht dargestellt sind, können beispielsweise aus metallischen Siebdruckstreifen bestehen, die auf die Einscheibensicherheitsglas-scheibe 14 und/oder die Dekorscheibe 16 aufgebracht sind. Die Dekorscheibe 16 steht über eine Verbundfolie 22 mit einer Trägerplatte 24 in Klebverbindung, welche bei dem hier gezeigten Ausführungsbeispiel aus klar transparentem Silikatglas besteht. As can be seen from the drawing, the solar module according to the invention in the exemplary embodiment shown there has an outer pane 10 which is made of silicate glass, specifically white glass. A single-pane safety glass pane 14 made of tempered silicate glass is bonded to the outer pane 10 via a plastic composite film 12, the structure and manufacture of which are explained in more detail below. With the toughened safety glass pane 14 and a decorative pane 16, which, like the toughened safety glass pane 14, also consists of tempered silicate glass and has been produced in the manner to be explained in more detail below, there is a laminated safety glass pane in the manner of the composite layer Plastic layer 18 in connection, for example formed as a cast resin layer in which a solar cell field 20, preferably consisting of polycrystalline solar cells, is embedded. The individual solar cells of the solar cell array 20 are not shown in the drawing, but are explained, for example, in DE-OS 4 029 822.1, e.g. also as known from EP-OS 0 382 060, interconnected by connecting conductors, further connecting conductors leading to the edge of the pane and serving for the electrical connection of adjacent solar modules. The connecting and connecting lines, which are not shown in the drawing, can consist, for example, of metallic screen printing strips which are applied to the single-pane safety glass pane 14 and / or the decorative pane 16. The decorative pane 16 is bonded via a composite film 22 to a carrier plate 24, which in the exemplary embodiment shown here consists of clearly transparent silicate glass.
Wie Fig. 1 erkennen lässt, weisen die Einschei-bensicherheitsglasscheiben 14, 16 eine Vielzahl von im wesentlichen senkrecht zur Modulebene, also in der Zeichnung im wesentlichen normal zur Aussenscheibe 10, verlaufenden inneren Bruchflächen 28 auf, die bei der Herstellung des Solarmoduls wie folgt vorzugsweise erzeugt sind: As can be seen in FIG. 1, the single-pane safety glass panes 14, 16 have a plurality of inner fracture surfaces 28 which run essentially perpendicular to the module plane, that is to say essentially normal to the outer pane 10 in the drawing, and which are preferably as follows when producing the solar module are generated:
Nachdem der Gesamtverbund in aus der Herstellung von Verbundsicherheitsglasscheiben bekannter Weise hergestellt worden ist, werden die Einschei-bensicherheitsglasscheiben 14, 16 vom Rand her z.B. mechanisch beansprucht, beispielsweise durch einen leichten Schlag mit einem spitzen Werkzeug, After the entire composite has been produced in a manner known from the production of laminated safety glass panes, the single-pane safety glass panes 14, 16 are e.g. mechanically stressed, for example by a light blow with a pointed tool,

wie einem Körner oder dergleichen, welcher an den dann noch freiliegenden Rand des Solarmoduls angesetzt wird, woraufhin das thermisch vorgespannte Material «zerkrümelt», wie dies z.B. von Scheiben für Kraftfahrzeuge bekannt ist, die aus Einscheibensicherheitsglas bestehen, wodurch sich die charakteristische Struktur mit im wesentlichen senkrecht zur Modulebene verlaufenden Bruchflächen 28 ergibt. such as a grain or the like, which is attached to the then still exposed edge of the solar module, whereupon the thermally pre-stressed material "crumbles", e.g. is known for windows for motor vehicles, which consist of single-pane safety glass, which results in the characteristic structure with fracture surfaces 28 extending essentially perpendicular to the module plane.
Die Bruchflächen 28 der Einscheibensicherheits-glasscheibe 14 verhindern dabei, dass das Solarmodul, z.B. bei Venwendung als Fassadenelement, bei der Betrachtung von der Aussenseite der Aus-senscheibe 10 her ein ästhetisch nicht gefälliges Äusseres hat, weil insbesondere die ansonsten oft störende «technische» Struktur der Solarzellen, insbesondere aber auch der Anschluss- und Verbindungsleitungen, weniger auffällig gemacht wird. Der durch die Einscheibensicherheitsglasscheibe 14 hervorgerufene Transparenzverlust ist dabei sehr gering, weil nämlich die Bruchflächen 28 der Ein-scheibensicherheitsglasscheibe 14 im wesentlichen senkrecht zur Modulebene verlaufen, so dass über einen grossen Bereich des Lichteinfallswinkels durch die Bruchflächen 28 der Einscheibensicher-heitsglasscheibe 14 praktisch keine Transparenzverringerung bewirkt wird. The fracture surfaces 28 of the single-pane safety glass pane 14 prevent the solar module, e.g. when used as a facade element, when viewed from the outside of the outer pane 10 has an aesthetically unappealing exterior, because in particular the otherwise often disruptive “technical” structure of the solar cells, but in particular also the connecting and connecting lines, is made less noticeable . The loss of transparency caused by the single-pane safety glass pane 14 is very small because the fracture surfaces 28 of the single-pane safety glass pane 14 run essentially perpendicular to the module plane, so that practically no reduction in transparency results from the fractured surfaces 28 of the single pane safety glass pane 14 over a large range of the angle of incidence of light becomes.
Die Dekorscheibe 16 deckt in ähnlicher Weise wie hinsichtlich ihres dekorativen Effektes die Ein-scheibensicherheitsglasscheibe 14 die Rückseite des Solarzellenfeldes 20 nebst Anschluss- und/oder Verbindungsleitungen «optisch» ab, so dass das Modul auch von der Rückseite her ein gefälliges Aussehen hat. In a manner similar to its decorative effect, the single-pane safety glass pane 14 covers the rear side of the solar cell array 20 together with connecting and / or connecting lines “optically”, so that the module also has a pleasing appearance from the rear.
